DESCRIPTION OF EMBODIMENTS

To make objectives, technical solutions, and advantages of this application clearer, the following further describes implementations of this application in detail with reference to the accompanying drawings. It is to be understood that the specific embodiments described herein are merely used for explaining this application but are not intended to limit this application.

First, the following explains several terms involved in the embodiments of this application.

Virtual environment: a virtual environment that is displayed (or provided) by an application when run on an electronic device (such as a terminal). The virtual environment may be a simulated environment of a real world, or may be a semi-simulated semi-fictional three-dimensional (3D) environment, or may be an entirely fictional 3D environment. The virtual environment may be any one of a two-dimensional virtual environment, a 2.5-dimensional virtual environment, and a 3D virtual environment. A description is made by using an example in which the virtual environment is a 3D virtual environment in the following embodiments, but this is not limited.

Virtual character: a movable object in a virtual environment. The movable object may be at least one of a virtual person, a virtual animal, and a cartoon person. Optionally, in a case that the virtual environment is a 3D virtual environment, the virtual character is a 3D model created based on skeletal animation technology. Each virtual character has a shape and size in the 3D virtual environment, and occupies some space in the 3D virtual environment.

Virtual object: an object displayed in the virtual environment. The object may be a movable object, for example, a virtual animal or a movable target; or may be an unmovable object, for example, a virtual building or a virtual hill. Optionally, the virtual object may be a 3D model. Each virtual object has a shape and size in the 3D virtual environment, and occupies some space in the 3D virtual environment.

Perspective: an observation angle for observation from a first-person perspective or a third-person perspective of a virtual character in a virtual environment. Optionally, in the embodiments of this application, the perspective is an angle for observing the virtual character by using a camera model in the virtual environment.

Optionally, the camera model automatically follows the virtual character in the virtual environment. That is, when a position of the virtual character in the virtual environment changes, a position of the camera model following the virtual character in the virtual environment changes simultaneously, and the camera model may be within a preset distance range from the virtual character in the virtual environment. Optionally, in the automatic following process, relative positions of the camera model and the virtual character remain unchanged.

A sight bead is set on a virtual picture within a perspective range. The sight bead is used as a reference for perspective rotation. Optionally, the sight bead is on the central axis of the perspective.

Camera model: a 3D model located around a virtual character in a 3D virtual environment. When a first-person perspective is adopted, the camera model is located near the head of the virtual character or at the head of the virtual character. When a third-person perspective is adopted, the camera model may be located behind the virtual character and bound to the virtual character, or may be located at any position at a preset distance from the virtual character. The virtual character located in the 3D virtual environment may be observed from different angles through the camera model. Optionally, when the third-person perspective is a first-person over-shoulder perspective, the camera model is located behind the virtual character (for example, the head and the shoulders of a virtual person). Optionally, in addition to the first-person perspective and the third-person perspective, the perspective also includes other perspectives, such as a top perspective. When the top perspective is used, the camera model may be located above the head of the virtual character. The top perspective is a perspective for observing the virtual environment at an angle from the air. Optionally, the camera model is not actually displayed in the 3D virtual environment. In other words, the camera model is not displayed in the 3D virtual environment displayed in a user interface (UI).

The first-person perspective or the third-person perspective may be adopted for implementation of a method for generating mark information in a virtual environment provided in this application. The method is applicable to a computer system shown in FIG. 1. The computer system 100 includes a first terminal 120, a server 140, and a second terminal 160.

The server 140 includes at least one of one server, a plurality of servers, a cloud computing platform, and a virtualization center. For example, the server 140 includes a processor (processing circuitry) 144 and a memory 142 (non-transitory computer-readable memory). The memory 142 includes a theme storage module 1421, a message and interaction storage module 1422, and a notification distribution module 1423. The server 140 is configured to provide a backend service for an application supporting a 3D virtual environment. Optionally, the server 140 takes on primary computing work, and the first terminal 120 and the second terminal 160 take on secondary computing work; alternatively, the server 140 takes on secondary computing work, and the first terminal 120 and the second terminal 160 take on primary computing work; alternatively, collaborative computing is performed by using a distributed computing architecture among the server 140, the first terminal 120, and the second terminal 160.

An application supporting a virtual environment is installed and run on the second terminal 160. The application may be any one of a virtual reality application, a 3D map program, a military simulation program, a TPS game, an FPS game, a MOBA game, a multiplayer gunfight survival game, and a battle royale shooting game. The second terminal 160 is a terminal used by a second user, and the second user uses the second terminal 160 to control a second virtual character in the virtual environment to perform a movement. The movement includes, but is not limited to, at least one of body posture adjustment, crawling, walking, running, cycling, jumping, driving, picking-up, shooting, attacking, and throwing. For example, the second virtual character is a second virtual person, such as a simulated person role or a cartoon person role.

Optionally, the first virtual character and the second virtual character are located in the same virtual environment. Optionally, the first virtual character and the second virtual character may belong to the same team or the same organization, have a friend relationship, or have temporary communication permission.

Optionally, the applications installed on the first terminal 120 and the second terminal 160 are the same, or the applications installed on the two terminals are the same type of applications in different control system platforms. The first terminal 120 may be generally one of a plurality of terminals, and the second terminal 160 may be generally one of a plurality of terminals. In this embodiment, only the first terminal 120 and the second terminal 160 are used as an example for description. The first terminal 120 and the second terminal 160 are of the same or different device types. The device type includes at least one of a smartphone, a tablet computer, an e-book reader, an MP3 player, an MP4 player, a laptop, and a desktop computer. The following embodiment is described by using an example that the terminal includes a smartphone.

A person skilled in the art may understand that there may be more or fewer terminals. For example, there may be only one terminal, or there may be dozens or hundreds or more terminals. The quantity and the device type of the terminals are not limited in the embodiments of this application.

FIG. 2 is a flowchart of a method for generating mark information in a virtual environment according to an exemplary embodiment. The method is applicable to an electronic device. The electronic device may be a terminal or server shown in FIG. 1, and a description is made by using an example in which the method is applied to the terminal shown in FIG. 1. The method includes the following steps:

In step 201, a terminal displays a target-perspective picture.

In an embodiment, the terminal displays a target-perspective picture of an application. The application may be at least one of a virtual reality application, a 3D map application, a military simulation program, a TPS game, an FPS game, and a MOBA game.

The target-perspective picture is a picture obtained by observing the virtual environment including a virtual character from a target perspective. Optionally, the target perspective is a perspective for observing the virtual environment from a first-person perspective of the virtual character, or the target perspective is a perspective for observing the virtual environment from a third-person perspective of the virtual character.

A sight bead and a mark control are displayed in the target-perspective picture.

The sight bead is used as a reference for the perspective. Optionally, the sight bead is displayed in a middle position of the target-perspective picture. In this embodiment, the sight bead is used for position aiming.

The mark control (mark control interface) is configured to trigger generation of mark information on a virtual object to which an aiming position points. Optionally, the mark control is a button control or a joystick control (joystick control interface). For example, FIG. 3 shows a joystick control, where the left part of the figure shows a joystick control 11 when no operation is triggered, and the right part of the figure shows a joystick control 12 when a drag operation is triggered.

Optionally, the mark information includes at least one of a warning mark, a material mark, a go-forward mark, an attack mark, a retreat mark, a defense mark, a caution mark, and a neutral mark.

The warning mark is used for prompting the virtual character to take warning measures, or prompting the virtual character to take warning measures for a marked position. The material mark is used for prompting the virtual character that there is a material in the marked position. The go-forward mark is used for prompting the virtual character to go forward to the marked position, or setting the virtual character to automatically go forward to the marked position; the attack mark is used for prompting the virtual character to start attacking, or prompting the virtual character to attack toward the marked position.

The retreat mark is used for prompting the virtual character to start retreating, or prompting the virtual character to retreat toward the marked position. The defense mark is used for prompting the virtual character to be in defense. The caution mark is used for prompting the virtual character that it is dangerous in the marked position, or prompting the virtual character that there is an enemy in the marked position. The neutral mark is used as a prompt mark, and can indicate agreed content to a user.

Optionally, a perspective switching control is further superimposed and displayed on the target-perspective picture. The perspective switching control is configured to control switching of the perspective of the virtual character, and is further configured to change an aiming position of the sight bead.

In step 202, the terminal receives a first-perspective switching operation.

The terminal includes a touch screen, and receives a first-perspective switching operation triggered by the user in a screen region corresponding to the perspective switching control. The first-perspective switching operation is used for changing an observation direction of the target-perspective picture and the aiming position of the sight bead.

In step 203, the terminal changes an observation direction of the target-perspective picture and an aiming position of a sight bead according to the first-perspective switching operation.

The terminal changes the perspective of the virtual character according to the first-perspective switching operation, to change the observation direction of the target-perspective picture and the aiming position of the sight bead. The change of the aiming position of the sight bead is used for determining a position of the virtual object.

In step 204, the terminal receives a mark operation triggered on a mark control.

The terminal receives a mark operation triggered by the user in a screen region corresponding to the mark control. The mark operation is used for triggering generation of mark information on the virtual object to which the aiming position points.

Optionally, when the mark control is a button control, the mark operation may be any one of a tap operation, a double-tap operation, and a multi-tap operation.

Optionally, when the mark control is a joystick control, the mark operation may be at least one of a tap operation and a slide operation.

In step 205, the terminal generates, according to the mark operation, mark information on a virtual object to which the aiming position points.

The terminal determines the virtual object in a pointing direction of the aiming position, and generates mark information on the virtual object.

Optionally, when the mark control is a button control, the terminal generates, according to the mark operation, the mark information on the virtual object to which the aiming position points.

Optionally, when the mark control is a joystick control, the mark operation includes a slide operation acting on the joystick control; and generation of the mark information includes the following schematic steps.

(1) The terminal superimposes and displays a roulette option list on the target-perspective picture in response to a determination that the joystick control receives the slide operation.

The roulette option list includes at least two candidate mark types arranged along a roulette edge. Optionally, the at least two candidate mark types include at least two of the following types: a warning mark, a material mark, a go-forward mark, an attack mark, a retreat mark, a defense mark, a caution mark, and a neutral mark.

(2) The terminal determines a target mark type from the at least two candidate mark types according to an end position of the slide operation.

Optionally, a slide region of the joystick control includes a roulette region, and the roulette region is divided into M subregions, a candidate mark type being correspondingly set in each of the M subregions. The terminal determines that a subregion in which the end position of the slide operation is located is an i^(th) subregion, and determines an i^(th) candidate mark type corresponding to the i^(th) subregion as the target mark type, M being a positive integer greater than 1, i being a positive integer less than or equal to M.

For example, the slide region of the joystick control includes a subregion 1, a subregion 2, a subregion 3, and a subregion 4. A mapping relationship between the subregions and candidate mark types is shown in Table 1. An attack mark is correspondingly set in the subregion 1, a retreat mark is correspondingly set in the subregion 2, a defense mark is correspondingly set in the subregion 3, and a caution mark is correspondingly set in the subregion 4.

When the end position of the slide operation is located in the subregion 1, the target mark type is the attack mark. When the end position of the slide operation is located in the subregion 2, the target mark type is the retreat mark. When the end position of the slide operation is located in the subregion 3, the target mark type is the defense mark. When the end position of the slide operation is located in the subregion 4, the target mark type is the caution mark.

TABLE 1 Subregion Candidate mark type List item 1 Attack mark 1 2 Retreat mark 2 3 Defense mark 3 4 Caution mark 4

The M subregions respectively correspond to M list items in the roulette option list. The terminal displays the M candidate mark types in the M corresponding list items respectively. In other words, the i^(th) subregion corresponds to an i^(th) list item, and when triggering a slide operation of the joystick control, the terminal displays the candidate mark type corresponding to the i^(th) subregion in the i^(th) list item. For example, as shown in Table 1, when triggering a slide operation of the joystick control, the terminal displays the attack mark corresponding to the subregion 1 in a list item 1, displays the retreat mark corresponding to the subregion 2 in a list item 2, displays the defense mark corresponding to the subregion 3 in a list item 3, and displays the caution mark corresponding to the subregion 4 in a list item 4.

(3) Generate the mark information corresponding to the target mark type on the virtual object to which the aiming position points.

Optionally, the terminal projects a ray in a forward direction from the aiming position, and determines an intersection position between the ray and a map scene or the virtual object in the virtual environment. The terminal then generates the mark information corresponding to the target mark type on the intersection position. The ray is not visible in the virtual environment; or the ray is a fully or partially visible ray in the virtual environment.

For example, the mark control is a joystick control. As shown in FIG. 4, a sight bead 22 and a joystick control 23 are displayed in a target-perspective picture 21. The terminal receives a slide operation on the joystick control 23, and superimposes and displays a roulette option list 25 on a target-perspective picture 24, the roulette option list 25 including four candidate mark types arranged along a roulette edge, which are a caution mark 1, a go-forward mark 2, a material mark 3, and a neutral mark 4 respectively. When an end position of the slide operation is a position 26 shown in the target-perspective picture 24, the target mark type corresponds to the neutral mark 4 (a shaded part in the figure) in the roulette option list 25. The terminal projects a ray in a forward direction of the aiming position, and determines an intersection position 31 with a map scene in the virtual environment. As shown in FIG. 5, the neutral mark 4 is displayed on the intersection position 31.

Optionally, when the mark control is a joystick control, the mark operation includes a tap operation acting on the joystick control; and when receiving the tap operation on the joystick control, the terminal generates mark information on the virtual object to which the aiming position points.

Mark information of the corresponding different mark types in the roulette option list may be set by the user, or may be default in the application. The mark information generated by triggering of the tap operation may also set by the user, or be default in the application. For example, assuming that settings in Table 1 are default in the application, the user may set mark information corresponding to the subregion 1 to a material mark, and then the material mark is correspondingly displayed in the list item 1. It is assumed that when a tap operation is triggered on the joystick control, the terminal generates a neutral mark by default, and the user can change the setting, to set mark information corresponding to a tap operation to a go-forward mark, so that when a tap operation is triggered on the joystick control, the terminal generates a go-forward mark.

Based on the above, by means of the method for generating mark information in a virtual environment provided in this embodiment, a target-perspective picture of an application is displayed on a terminal, a sight bead and a mark control being displayed in the target-perspective picture; and the terminal receives a first-perspective switching operation, changes an observation direction of the target-perspective picture and an aiming position of the sight bead according to the first-perspective switching operation, receives a mark operation triggered on the mark control, and generates, according to the mark operation, mark information on a virtual object to which the aiming position points.

The method can enable the terminal to generate the mark information on the virtual object without interrupting other operations of a virtual character, thereby improving human-computer interaction efficiency. In addition, by means of the method, a position of the virtual object is determined by using a ray emitted by the sight bead, so that marking on the virtual object is more accurate, and a long-distance virtual object can also be accurately marked. In addition, by means of the method, one joystick control can be used to trigger marking of mark information of at least two mark types, so that it is unnecessary to set a plurality of mark controls, to avoid affecting control operations on a screen and avoid increasing an erroneous touch rate. It is unnecessary to unfold an option list to select a mark type of mark information, thereby implementing quick marking of mark information of different mark types, and improving human-computer interaction efficiency.

Based on FIG. 2, after the user triggers the mark operation, the mark operation may be cancelled. As shown in FIG. 6, an example in which the mark control is a joystick control, and the mark operation includes a slide operation acting on the joystick control is used. The method for generating mark information in a virtual environment may further include the following steps:

In step 301, a roulette option list is superimposed and displayed on the target-perspective picture in response to a determination that the joystick control receives the slide operation.

The roulette option list includes at least two candidate mark types arranged along a roulette edge and a central region.

In step 302, generation of the mark information is canceled in response to a determination that an end position of the slide operation is in the central region.

Optionally, an operation region corresponding to the joystick control is divided into a roulette region and a central region, for example, two concentric circles, including an inner circle and an outer circle, a region included in the inner circle being the central region, a region out of the inner circle and inside the outer circle being the roulette region. In a case that an end position of the slide operation is in the central region, the terminal cancels generation of the mark information.

For example, as shown in FIG. 7, in the target-perspective picture 24, the position 26 at which a joystick is located is in the roulette region, and a corresponding mark type in the roulette option list is the neutral mark 4. When the slide operation ends in the position 26, mark information generated correspondingly is the neutral mark 4. Before the slide operation ends, the joystick is slid to a position 41. As shown in a target-perspective picture 42 in the figure, the position 41 is located in the central region, and when the slide operation ends in the position 41, generation of the mark information is cancelled. A cancel mark 43 is further displayed in a central position of the roulette option list.

Based on the above, according to the method for generating mark information in a virtual environment provided in this embodiment, after the operation of triggering generation of the mark information, generation of the mark information can be cancelled, so that an erroneous operation can be cancelled in time after being triggered by the user, thereby improving user operation experience.

In addition, the method resolves a problem that mark information can only be used for marking geographic locations on a map, and cannot be used for marking in other dimensions, so that the terminal can mark virtual objects such as virtual props in the virtual environment.

The mark information may be cancelled after an operation of generating mark information is triggered, and may alternatively be cancelled after the mark information is successfully generated. Based on FIG. 2, step 206 to step 210 are added after step 205. As shown in FIG. 8, schematic steps are as follows:

In step 206, a second-perspective switching operation is received.

The second-perspective switching operation may further be used for aiming the sight bead at existing mark information.

In step 207, the sight bead is aimed at existing mark information according to the second-perspective switching operation.

Optionally, schematic steps of aiming the sight bead at existing mark information by the terminal may as be follows. (1) The terminal adjusts the aiming position of the sight bead according to the second-perspective switching operation. (2) The terminal calculates a first distance between the aiming position and a marked position of the existing mark information. (3) The terminal determines whether the first distance is less than a first distance threshold; and, in response to a determination that the first distance is less than the first distance threshold, the terminal performs step 208; otherwise, the terminal performs step (1).

In step 208, a cancel control (cancel control interface) is superimposed and displayed on the target-perspective picture in response to a determination that the sight bead is aimed at the existing mark information.

The cancel control is configured to cancel marking of the mark information. Optionally, the cancel control is a button control.

Optionally, in response to a determination that the first distance between the aiming position of the sight bead and the marked position of the existing mark information is less than the first distance threshold, the terminal displays a cancel control on the target-perspective picture.

Optionally, in response to a determination that the virtual character has a teammate, the existing mark information may be mark information marked by the virtual character or mark information marked by the teammate.

In step 209, a cancel operation triggered on the cancel control is received.

Optionally, in response to a determination that the cancel control is a button control, the cancel operation may be a tap operation on the cancel control; and the terminal receives the tap operation on a screen region corresponding to the button control.

In step 210, displaying of the existing mark information is canceled according to the cancel operation.

For example, as shown in FIG. 9, when the sight bead is aimed at a marked position 52 of the mark information, a cancel button 53 is displayed on a target perspective interface 51, as shown in the upper part of the figure. The terminal receives a tap operation on the cancel button 53, and the mark information is no longer displayed on the marked position 52 in the target perspective interface 51, as shown in the lower part of the figure.

In response to a determination that the existing mark information is marked by a teammate of the virtual character, when the cancel control is displayed on the target-perspective picture, a response control (response control interface) may further be displayed, the response control being configured to respond to the mark information of the teammate. For example, when the mark information marked by the teammate of the virtual character is an attack mark, the virtual character responds to the mark information by using the response control, to inform the teammate that the user controlling the virtual character has received an attack message.

Based on the above, according to the method for generating mark information in a virtual environment provided in this embodiment, mark information can be cancelled after being generated, so that the user can cancel marking of the mark information at any time, thereby improving the user operation experience.

Based on FIG. 2, a method for determining a mark type of the mark information is described by using an example in which the mark control is a joystick control, and the mark operation is a slide operation on the joystick control. The roulette option list includes four candidate mark types. As shown in FIG. 10, schematic steps are as follows:

In step 401, a slide operation triggered on a joystick control is received.

The terminal receives the slide operation triggered on the joystick control.

In step 402, position coordinates of a joystick in the joystick control are read.

Optionally, by using an example in which a slide region of the joystick control is circular, a rectangular coordinate system is established by using a center point of the slide region as the origin, and position coordinates (X, Y) of the joystick after being slid are read, that is, a horizontal coordinate is X, and a vertical coordinate is Y.

In step 403, a second distance between the position coordinates and the origin is calcualated.

The terminal calculates the second distance L between the position coordinates (X, Y) and the origin, where a calculation formula is L=√{square root over (X²+Y²)}.

In step 404, it is determined whether the second distance is greater than a second distance threshold.

The terminal determines whether the second distance L is greater than the second distance threshold R. As an exemplary description, a concentric circle is set inside the circular region corresponding to the slide region, and R is the radius of the concentric circle.

When L is greater than R, step 405 is performed; and when L is less than or equal to R, step 418 is performed.

In step 405, it is determined whether the slide operation ends.

The terminal determines whether the slide operation ends; when the slide operation does not end, the terminal performs step 406; and when the slide operation ends, the terminal performs step 415.

In step 406, it is determined whether a horizontal-axis coordinate is positive or negative.

The foregoing embodiment is based on a game application scenario, and the following is a brief description of an example of an embodiment of military simulation.

The simulation technology is a model technology in which a system behavior or process is reflected by using software and hardware through an experiment of simulating a real environment.

A military simulation program is a program specially constructed for military application by using simulation technology, which performs quantitative analysis on battle elements such as sea, air, and land, weapon equipment performance, battle actions, and the like, to accurately simulate a battlefield environment, and present a battlefield situation, thereby implementing battle system evaluation and decision aids.

For example, a user establishes a virtual battlefield on a terminal in which a military simulation program is located, and a battle is performed between groups. The user controls a virtual character in the virtual battlefield environment to perform at least one operation of walking, running, climbing, driving, shooting, throwing, detecting, close combat, and other actions in the virtual battlefield environment. The virtual battlefield environment includes at least one of the following forms: a plain, a mountain, a plateau, a basin, a desert, a river, a lake, a sea, vegetation, and a building. Virtual characters include a virtual person, a virtual animal, a cartoon person, and the like. Each virtual character has a shape and size in a 3D virtual environment, and occupies some space in the 3D virtual environment.

Based on the above situation, optionally, when needing to send a prompt to a teammate, the user may determine a target position on a target-perspective picture of the military simulation program, and marks corresponding mark information. For example, the user makes a material mark on a position of a material, to prompt the teammate that the material can be picked up here; or the user makes an enemy mark on an enemy, to prompt the teammate that the virtual character belongs to an enemy camp; or the user makes a caution mark in a dangerous region ahead, to prompt the teammate that it is dangerous ahead. For a method for generating mark information in a military scenario, refer to the foregoing scenario of generating mark information based on the game application scenario, and details are not described herein again.

Moreover, at least some of the steps in FIG. 2, FIG. 6, FIG. 8, and FIG. 10 may include a plurality of sub-steps or a plurality of stages. These sub-steps or stages are not necessarily performed at the same moment, but may be performed at different moments. These sub-steps or stages are not necessarily executed sequentially, but may be performed in turn or alternately with another step or at least some of sub-steps or stages of another step.

Based on the above, by means of the apparatus for generating mark information in a virtual environment provided in this embodiment, a target-perspective picture of an application is displayed by the apparatus, a sight bead and a mark control being displayed in the target-perspective picture; a first-perspective switching operation is received. An observation direction of the target-perspective picture and an aiming position of the sight bead are changed according to the first-perspective switching operation. A mark operation triggered on the mark control is received, and mark information is generated, according to the mark operation, on a virtual object to which the aiming position points. The apparatus can generate the mark information on the virtual object without interrupting other operations on a virtual character, thereby improving human-computer interaction efficiency. In addition, the apparatus determines a position of the virtual object by using a ray emitted by the sight bead, so that marking on the virtual object is more accurate, and a long-distance virtual object can also be accurately marked. In addition, by means of the apparatus, one joystick control can be used to trigger marking of mark information of at least two mark types, so that it is unnecessary to set a plurality of mark controls, to avoid affecting control operations on a screen and avoid increasing an erroneous touch rate. It is unnecessary to unfold an option list to select a mark type of mark information, thereby implementing quick marking of mark information of different mark types, and improving human-computer interaction efficiency.

In addition, the apparatus further resolves a problem that mark information can only be used for marking geographic locations on a map, and cannot be used for marking in other dimensions, so that virtual objects such as virtual props in the virtual environment can be marked by using mark information.
